' To all whom it may concern:

ice-covered surfaces of walks or pavements,

particularly the sidewalks of cities or towns where a rapid spreading of such material is desirable, the object 'of the invention being to provide a device of this kind which will be simple in construction, and `which. will act to spread the material uniformly upon such surfaces, and whereby such spreading may be accomplished rapidly and at a minimum cost.

The invention comprises briefly a hopper or receptacle mounted upon a carrying .device adapted to be drawn or propelled along the surface upon which the material is to be spread and provided with means adapted to be automatically actuated by such movement of the carrier whereby the discharge of the material from the hopper upon such surface is effected. 1

For full. comprehension, however of our l invention reference must be had to the accompanying drawings forming a part of this specification, in which similar reference characters indicate the same parts and where m- Figure 1v is a planview of our device; F ig. 2 is a longitudinal sectional view thereof taken on line 2 2 Fig. l; and Fig. 3 is an enlarged detail sectional view taken on lilie 3-3 Fig. 1. Y

Our improved device comprises a hopper 2 in which the material to be spread is placed, such hopper having the lower. portion ofv two of its walls converging downwardly as shown at 3, the bottom of the hopper' being constituted by a plate 4 having perforations 5 through-Which the material 1s discharged from the ho per. rThis hopper is mounted upon a suita le carrier adapted to be drawn or propelled by suitable means over the surface upon which the material is spread. This carrier as here shown is in the form of an open top sled having runners b connected by cross-braces 7 and having a seat 8 for the operator, `such sled being adapted to be provided with a suitable draft attachrnent not necessary here to be shown, whereby it may be drawn over the surface upon which the material is to be spread, the hopper being supported near the front end of the sled .upon cross bars 1l resting at opposite ends upon the runners 6.

ln order to insure a constant and even discharge of the material through the perforations 5 a horizontally arranged grille-like frame or member, which may be termed a shaker, is located above the bottom 4 and adapted to be reciprocated thereacross, such frame or member being composed of the side and center longitudinal bars l2 and 13 respectively, connected by cross-pieces 14,

which latter as they are moved to and fro across the bottom plate 4 edect an agitation or shaking of the vmaterial necessary to cause it to'discharge through the' perforations in the plate; the. longitudinal bars, which serve as supports for the cross-bars being supported in suitable slots or openings indicated at 14 in the inclined portions of the hopper walls, the side bars l2 having rearward eX- tensions 15 passing freely through eyes 16 secured to the runners 6 and serving to guide the frame in its reciprocation. This frame or shaker is reciprocat/ed from a drive shaft '20 cranked as at 2l, to which crank is suitably connecteds as by the strap 22, one end of a Y-shaped connectin rod 3, the opposite or branched end o the rod 23 being connected as at-24'lto a cross-head 25 extending betweenand connected to the rearward extensions l5.

Shaft 20 is adapted to be rotated when the sled is in motion by,.a. pair of drive wheels 30 preferably loose on said shaft and each carryin a pawl 30a. engaging a-ratchet wheel 30b rigid upon the shaft, this arrangement 'permitting variation in the rotation of the wheels when the device is moving around a corner or otherwise following an irregular course, these wheels each having its peripheryformed with teeth or spikes 31 which engage the surface over which the sled is traveling. In order that the toothed drive wheels may be moved when desired into or out of engagement with such surface, we prefer to mount the shaft 20 upon the free ends of a pair of swinging arms 32 hinged at their opposite ends to the sled7 being here over which the sled is passing.

aoV

The means for swinging the arms 32 to move the wheels 30 into or out of operative position as here shown comprisesan operators lever 40 branched as at 41, such branches being fulcrumed as at 42.to standards 43 upon the angle bar 34 while the ends of the branches 41 are connected by links 44 'to the arms 32, the lever being retained with the drive wheels 30 in operative position, asshown in fulllines in Fig. 2, between the top of a U-bracket 45 carried-by one of the cross bracketsl 7, and a removable pin 46 supported in such bracket. To raise the drive wheels out of operative position the lever 40 is swung to the position indicated in dotted lines and the pin 4 6 inserted through t-he opening 49 in such bracket. The lever is thus adapted to suspend the drive shaft when desired in position with the toothedwheels clear of the surface upon which the sled restsor along which it may be moving. e

'In operation the arts are in the position shown in full lines 1n Fig. 2 with the spikes in the wheel projecting below the bottom of the sled runners and into engagement with the surface on which'the sled rests, and as the sled moves over the surface the engagement `of the teeth or spikes 3l therewlth causes the wheel 30 to rotate, thus reciprocating by means of cranked shaft 20 and connecting rod 23 the grille-like frame or shaker located above the perforated bottom 4, the moving of this frame across such bottom causing a revular discharge of material therethrou h and upon the surface over which the evice passes.

What we claim Ais as follows l. A device for-spreading cinders upon a snow or ice covered surface, comprising a carrier adapted to be moved along the said surface and to be supported at opposite sides thereon, a hopper for containing the cinders mounted upon the carrier and having its bottom extending between the opposite sides of the carrier and formed' throughout its width with vertically extendi perforations, a reciprocatory shaker carried by the hopper and adapted to reciprocate in a direction parallel to the direction of travel of the carrier and having a bar extending transversely to its direction of reciprocation within the hopper adjacent its bottom and from side to side thereof and adapted to act upon the cinders in the hopper to cause them to be discharged through the said perforations, a bodily movable cranked shaft mounted upon the carrier, a connecting rod connect-ing such shaft to -the shaker, a toothed drive wheel mounted upon the shaft, and means whereby such drive wheel may be either locked in 4position engaging the said surface or suspended thereabove.

2. A device for spreading cinders upon a 'snow or ice-covered surface, comprising a `within the hopper adjacent itsl bottom and from side to side thereof and adapted to act upon the cinders in the hopper to cause them to be discharged through the said perforationsa bodily movabledrive shaft extending between opposite sides of the carrier and having its central portion cranked, a pair of toothed drive wheels mounted one on each Iend of the saidcranked shaft, and a branched connecting rod operatively connecting the cranked shaft and shaker, the branches of the connecting rod divergin laterally and connecting at their separate ends to the shaker to cause operating power to be applied thereto near opposite sides thereof, and means for positively retaining thesaid shaft in position with the drive Wheels inor out of engagement with the said surface. I

3. A device for spreading cinders upon a snow or ic'e covered surface, comprising a sled having a pair of runners spaced laterally from one another and connected by cross braces, a hopper supported upon the sled and extending between the runners, such hopper having an oblong perforated bottom with its greatest dimension transverse to the sled and equal to the space between the runners, the said bottom bein formed to present perforations dispose `throughout the transverse length thereof, a

reciprocatory shaker carried by the hopper within the lat-ter above and adjacent the said bottom and havingvbars extending longitudinallyand transversely to its direction of reciprocation, the said transverse bars eX- tendine' from side to side of the hopper, guiding rods projecting from the shaker longitudinally of the sled on opposite sides thereof, guiding members carried by the runners and encircling the said rods, a drive shaft extending between opposite sides of the sled and having the central portion thereof cranked, a connecting rod connected at one end to the said orankthe opposite end being forked with laterally extending branches connecting to the said shaker,- means supporting such shaft whereby it may 5 be raised or lowered, a pair of toothed drive wheels mounted one on each end `of the shaft and adapted when the shaft is lowered to engage with the said surface, ratchet and pawl connections" between the shafts and l0 wheels whereby operative engagement will be effected between such shaft and wheels lupon rotation ofthe Wheels in one direction only, and means for positively retaining the said shaft in raised or lowered position.

In testimony whereof, We have signed 15 our names to this specification, in the presence of two subscribin witnesses.
